31、es,she is.五、过去进行时五、过去进行时 一、概念：表示过去某一时刻或某一时间内正在进行或发生的动作。可以从两个方面来理解：1.过去某一时刻正在进行或发生的动作。e.g.They were playing football at ten oclock yesterday morning.2.过去某阶段持续进行的动作 What were you doing during the holiday？另外，在复合句中，若主要动作和背景动作是同时发生的，那么主从句都可用过去进行时 e.g.Jenny was reading while Danny was writing.其结构是助动词be的过去

32、形式was/were+v-ing.其句式变化仍然要在be上做文章。e.g.We were working in class.We werent working in class.3.过去进行时常与过去某一特定时间的状语连用，last night,at that time，at noon yesterday，last Sunday 等。也有时没有间状语，要通过上下文的暗示来确定用过去进行时。e.g.The students all worked hard.Everyone knew what he was working for.做题时常见错误如下：一、易把be+现在分词记成be+过去分词 例：

33、He was talked（talk）to his mum at that time.答案：was talking 解析：过去进行时与现在进行时结构上的区别体现在be动词上。二、丢掉be动词或忘记把动词变成现在分词 例：1.I watching（watch）TV when he came in.2.They were play（play）games at 5：00 p.m.yesterday.答案：1 was watching 2 were playing 解析：现在进行时中“be+现在分词，缺一不可”的规律也可用于过去进行时。三、对动词或动词词组提问时丢掉doing 例：We were fl

34、ying kites at 5：00 p.m.yesterday.（对划线部分提问）What were you at 5：00 p.m.yesterday？答案：What were you doing at 5：00 p.m.yesterday？解析：现在进行时中“Whatdoing”？句式同样适用于过去进行时。四、易与现在进行时弄混例：My mother is cooking（cook）when I got home.答案：was cooking 解析：这两种时态的共同点是都表示动作正在进行，但现在进行时前提是现在，而过去进行时前提是过去，由when I got home可看出前提是过去。五

35、、易与一般过去时弄混例：昨晚我在读一本故事书。I read（read）a story book yesterday evening.答案：was reading 解析：这两种时态的共同点是都用于表示过去发生的动作。但过去进行时强调动作过去正在进行，而一般过去时则表示过去某一时间所发生的动作或存在的状态，它表示的动作往往已经完成。“在”说明正在进行，而“I read a story book yesterday evening.”的意思是昨晚我读了一本故事书，言下之意已经读完了。故用过去进行时。另外，在宾语从句中当主句为过去时，从句若是现在进行时，需变成过去进行时。e.g.He said tha

36、t he was drawing a cat at noon yesterday.专项训练：专项训练：一、单选 1.What _ from three to four yesterday afternoon？A have you done B had you done C did you do D were you doing 2.I call you yesterday evening，but there was no answer.-Oh.，Im sorry I _ dinner at my friends home.A home B had C was having D have had

38、tch D watched 6.She asked him whether he _ back for lunch.A come B was coming C came D had come 7.Could you tell me when _？A she is coming B she was coming C will be come D is he coming8.The teacher _ when I came into the classroom.A is drawing B draws C has drawn D was drawing 二、填空1._ they_（feed）th

39、e animals at 5:00 yesterday afternoon？2.Mrs.Green _ _（not wash）clothes at this time yesterday.3.Grandpa _ _（mend）his clock when I reached home.4.As I _（walk）in the park，I saw some children playing games.5.It was warm,so I _(take)off my coat.6.Jane _(wait)for me when I _(arrive).7.Sue wasnt hungry,so

40、 she _(eat)anything.三、根据汉语提示完成句子。1 他们那时不在打排球。They _ _ volleyball at that time.2 当你回来时，他在看电视吗？_ he _ TV when you came back?3 昨天中午他在哪里等你？_ _ he _ for you at noon yesterday?4 当我离开时，他正在做家庭作业。He _ _ his homework when I left.5.正当他们扫地的时候，老师进来了。While they_ _ the floor,the teacher came in.六、完成时态六、完成时态 1.概念：过

41、去发生的动作对现在造成的影响或结果：强调结果 E.g:Yesterday I finished my homework,thats to say,I have finished my homework now.过去已经开始一直持续到现在的动作或状态：强调继续 E.g：I have lived here since 1990.2.现在完成时的构成 havehas+过去分词 3.现在完成时的四个基本句型 肯定句 He has finished the work.一般疑问句 Has he finished the work?否定句 He has not finished the work.两回答 Y
